The 10 inventions of Nikola Tesla That Changed the World

1.
Alternating Current -- This is where it all began, and what ultimately
caused such a stir at the 1893 World's Expo in Chicago. A war was
leveled ever-after between the vision of Edison and the vision of Tesla
for how electricity would be produced and distributed. The division can
be summarized as one of cost and safety: The DC current that Edison
(backed by General Electric) had been working on was costly over long
distances, and produced dangerous sparking from the required converter
(called a commutator). Regardless, Edison and his backers utilized the
general "dangers" of electric current to instill fear in Tesla's
alternative: Alternating Current. As proof, Edison sometimes
electrocuted animals at demonstrations. Consequently, Edison gave the
world the electric chair, while simultaneously maligning Tesla's attempt
to offer safety at a lower cost. Tesla responded by demonstrating that
AC was perfectly safe by famously shooting current through his own body
to produce light. This Edison-Tesla (GE-Westinghouse) feud in 1893 was
the culmination of over a decade of shady business deals, stolen ideas,
and patent suppression that Edison and his moneyed interests wielded
over Tesla's inventions. Yet, despite it all, it is Tesla's system that
provides power generation and distribution to North America in our
modern era.

2. Light -- Of course he didn't invent
light itself, but he did invent how light can be harnessed and
distributed. Tesla developed and used florescent bulbs in his lab some
40 years before industry "invented" them. At the World's Fair, Tesla
took glass tubes and bent them into famous scientists' names, in effect
creating the first neon signs. However, it is his Tesla Coil that might
be the most impressive, and controversial. The Tesla Coil is certainly
something that big industry would have liked to suppress: the concept
that the Earth itself is a magnet that can generate electricity
(electromagnetism) utilizing frequencies as a transmitter. All that is
needed on the other end is the receiver -- much like a radio.

3.
X-rays -- Electromagnetic and ionizing radiation was heavily researched
in the late 1800s, but Tesla researched the entire gamut. Everything
from a precursor to Kirlian photography, which has the ability to
document life force, to what we now use in medical diagnostics, this was
a transformative invention of which Tesla played a central role.
X-rays, like so many of Tesla's contributions, stemmed from his belief
that everything we need to understand the universe is virtually around
us at all times, but we need to use our minds to develop real-world
devices to augment our innate perception of existence.

4. Radio --
Guglielmo Marconi was initially credited, and most believe him to be
the inventor of radio to this day. However, the Supreme Court
overturned Marconi's patent in 1943, when it was proven that Tesla
invented the radio years previous to Marconi. Radio
signals are just another frequency that needs a transmitter and
receiver, which Tesla also demonstrated in 1893 during a presentation
before The National Electric Light Association. In 1897 Tesla applied
for two patents US 645576, and US 649621. In 1904, however, The U.S.
Patent Office reversed its decision, awarding Marconi a patent for the
invention of radio, possibly influenced by Marconi's financial backers
in the States, who included Thomas Edison and Andrew Carnegie. This also
allowed the U.S. government (among others) to avoid having to pay the
royalties that were being claimed by Tesla.

5. Remote Control --
This invention was a natural outcropping of radio. Patent No. 613809
was the first remote controlled model boat, demonstrated in 1898.
Utilizing several large batteries; radio signals controlled switches,
which then energized the boat's propeller, rudder, and scaled-down
running lights. While this exact technology was not widely used for some
time, we now can see the power that was appropriated by the military in
its pursuit of remote controlled war. Radio controlled tanks were
introduced by the Germans in WWII, and developments in this realm have
since slid quickly away from the direction of human freedom.

6.
Electric Motor -- Tesla's invention of the electric motor has finally
been popularized by a car brandishing his name. While the technical
specifications are beyond the scope of this summary, suffice to say that
Tesla's invention of a motor with rotating magnetic fields could have
freed mankind much sooner from the stranglehold of Big Oil. However,
his invention in 1930 succumbed to the economic crisis and the world war
that followed. Nevertheless, this invention has fundamentally changed
the landscape of what we now take for granted: industrial fans,
household applicances, water pumps, machine tools, power tools, disk
drives, electric wristwatches and compressors.

7. Robotics --
Tesla's overly enhanced scientific mind led him to the idea that all
living beings are merely driven by external impulses. He stated: "I
have by every thought and act of mine, demonstrated, and does so daily,
to my absolute satisfaction that I am an automaton endowed with power of
movement, which merely responds to external stimuli." Thus, the
concept of the robot was born. However, an element of the human
remained present, as Tesla asserted that these human replicas should
have limitations -- namely growth and propagation. Nevertheless, Tesla
unabashedly embraced all of what intelligence could produce. His
visions for a future filled with intelligent cars, robotic human
companions, and the use of sensors, and autonomous systems are detailed
in a must-read entry in the Serbian Journal of Electrical Engineering,
2006 (PDF).

8. Laser -- Tesla's invention of the laser may be
one of the best examples of the good and evil bound up together within
the mind of man. Lasers have transformed surgical applications in an
undeniably beneficial way, and they have given rise to much of our
current digital media. However, with this leap in innovation we have
also crossed into the land of science fiction. From Reagan's "Star
Wars" laser defense system to today's Orwellian "non-lethal" weapons'
arsenal, which includes laser rifles and directed energy "death rays,"
there is great potential for development in both directions.

9
and 10. Wireless Communications and Limitless Free Energy -- These two
are inextricably linked, as they were the last straw for the power elite
-- what good is energy if it can't be metered and controlled? Free?
Never. J.P. Morgan backed Tesla with $150,000 to build a tower that
would use the natural frequencies of our universe to transmit data,
including a wide range of information communicated through images, voice
messages, and text. This represented the world's first wireless
communications, but it also meant that aside from the cost of the tower
itself, the universe was filled with free energy that could be utilized
to form a world wide web connecting all people in all places, as well as
allow people to harness the free energy around them. Essentially, the
0's and 1's of the universe are embedded in the fabric of existence for
each of us to access as needed. Nikola Tesla was dedicated to
empowering the individual to receive and transmit this data virtually
free of charge. But we know the ending to that story . . . until now?
